Mathematician, astronomer, and physicist Carl Friedrich Gauss got
demagnetised on this day in 1855; the old unit of magnetism, the Gauss (G)
is named after him (so keep that in mind the next time you use your
selector magnets). Trivia: as a school-kid, his class was set the problem
of adding up all the numbers from 1 to 100 (the teacher must've been a bit
of a bastard). As the rest of the class laboured away with chalk and
board, young Carl realised that the sequence 1 + 2 + 3 + ... + 100 is the
same as (1 + 100) + (2 + 99) ... etc, which reduces to 101 + 101 + 101 ...
i.e. 101 * 50, and he turned in the only correct answer within minutes.
He went on to derive the general formula for sum(1..N), which is
(N*(N+1)/2).
But we gained Col. Paul Tibbets K4ZVZ in 1915; he is well-known as the
pilot of a certain B-29, the Enola Gay...
